Thanks, I was looking at that page actually, but was wondering if you had a personal email. I'll be back with a report if I get a reply.

In the meantime I did find this article with this quote by Dr. Campbell:

"I really believe that dietary protein both the kind and the amount is more significant as far as cholesterol levels are concerned than is saturated fat. Certainly it is more significant than dietary cholesterol. While we don't know how animal proteins have this effect, we do know that animal protein has a quick and major impact on enzymes involved in the metabolism of cholesterol."
